DAP makes a roof sealant in an caulk gun tube. I used it many years ago
after I installed a skylight in an existing asphalt shingle roof. I
don't know if it a polymer sealant, but it contains mineral spirits and
asphalt. I don't know which big box store I got it in, but the shingles
I had to lift are still stuck down.
